I heard it says "Hegt" instead of "Hert". It is just how you pronounc this?
So it is not the right R? Only software problem? Because it is happening in more words, like "Bord"...
No, it is correct, but not everyone speaks with that R. It depends from speaker to speaker.
FYI, cause I find this interesting, it doesn't accept hart, either. And that is okay.
the word "hart" is an old alternative word for "stag". so it may have not accepted it because it is an English word.
If Dutch ‘hert’ means any deer, then English ‘hart’ is different, since a hart must be male.
